It provides a reproducible method recognized by regulatory authorities. However, it does not define acceptance thresholds or a direct correlation with in vivo conditions. Manufacturers must therefore:<\/p>\n<ul>\n<li>supplement the analysis with numerical modeling<\/li>\n<li>establish their own acceptance criteria,<\/li>\n<li>incorporate the results into the MRI Safety Labeling in accordance with ASTM F2503 and FDA recommendations.<\/li>\n<\/ul>\n<p>When properly applied, the standard helps determine the conditions under which passive implants do not present an excessive thermal risk during an MRI examination.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The risk associated with radiofrequency (RF)-induced heating is often the most critical factor when assessing the safety of medical devices in MRI.
